Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72702, here are decompositions:

13 + 72689 = 72702
23 + 72679 = 72702
29 + 72673 = 72702
31 + 72671 = 72702
41 + 72661 = 72702
53 + 72649 = 72702
59 + 72643 = 72702
79 + 72623 = 72702

Showing the first eight; more decompositions exist.
